The selected server is not a valid managed Backup Exec server. But there is no CASO environment

Hello,

after upgrading from BE2010 to 2012 and moving the database over to the new server (external SQL2008 Database), everything seemed to work fine.

Last night, ~30 out of 70 jobs have turned into status: "Ready; The selected server is not a valid managed Backup Exec server.  The job may be retargeted."

But there has never been a CAS option neither on the old system nor on the new one. I tried to fix it with doing the db maintenance tasks with BEUtility (repair, compress and re-organizing the indicies) without any effect.

I am still not able to run the jobs. If i do, there is no error message but it just won't start.

Any hints will be appreciated ;)

Regards

Ben
